What star is like the sun?

Answer 1

It's obvious that if you know the mass of a star, you'll know its mass. But you'll also be able to look into the future life of that star and make and educated guess as to how long it may live and how its life may end. Larger stars generally go through their fuel supply more rapidly and end up self-destructing in a supernova. Smaller stars burn their fuel more slowly and live a longer, and relatively more "quiet" life, and end up "burning out" and cooling to a "cinder" of some kind.

Answer 2

Note that it is really our sun, not just my sun - everyone on Earth has the same sun. The sun is just like the stars. The sun and stars are all huge balls of super-heated gas. The only real difference is that the sun happens to be a lot closer to us than the stars are.

Answer 3

It tells you how much material is in the star. It also determines how long the star will last. If the star is in its main sequence stage mass will also determine the star's temperature, color, and brightness.

Answer 4

Determining the mass of the star accurately is only possible with binary stars or stars with objects orbiting around them, usually planets.

By observing the motion of the two objects it's possible to determine mass of both objects, using Kepler's 3rd law [See related link]

For other stars, an approximation is made based on the type of star, it's radius and comparing it with other stars of a similar type and of a known mass.

Answer 5

This is a hard one. when a star dies thetre is a chemical gas exchange. then it dessolves in space. so its hard to say what they are made of. unless NASA can come up wth an idea to capture a star while it is alive . watch it die in a labatory that is thigth airseal .

Answer 6

It is scientifically proven the Sun is indeed a star. How we know is that the Sun is a big, glowing ball of energy and gas, produces heat, and has characteristics of other stars. Stars are and were formed the same way as the Sun, during an explosion of different gasses in space. The Sun is also working it's way to become a red giant, such as other stars, then explode to form a white dwarf in a supernova, then that will form more stars. That is indeed how we know the Sun is a star.

Answer 7

The sun is in the main sequence of the HR diagram with 90% of other stars. It is also the same size and color as other stars, and is middle aged.

Answer 8

By looking at its size, and then using a spectrograph to see what elements a certain star is made up of, and then applying the weightsd of those elements to how big the star is.

Answer 9

The Sun is a fairly average star. Like many other stars, the Sun produces energy. It emits light and heat.

Answer 10

Our Sun is basically an average star - nothing special about it. It's not a massive star and it's not a red dwarf, which is thankful as if it wasn't we wouldn't be around to appreciate it.
